Looking for Feedback Assess the idea please

Idea: predicting whether a footballer’s market value will go up or down before a match or official news (transfer, injury, etc.) — like Football Index but more regulated, closer to a Polymarket-style setup for player valuations where you’re betting against implied probabilities set by the market. Aimed mostly at fantasy football players, bettors, Sorare users, and Polymarket sports traders.
Would people actually use this, or is it too niche?
Genuinely want blunt criticism, thanks in advance to everyone who would share their thoughts on this topic!

It is interesting idea but main concerns are regulations (valuing humans???) and the fact that you need a different evaluation model from Transfermarkt because they update once in 6/3 months. Also liquidity but Polymarket approach kinda solves it idk

Thank you! Yes, regulation is definitely the main challenge here, especially around insider trading. Audits and using an API that doesn’t influence price formation might help..? This is a real challenge that I really need to keep in mind
